For more information about the author, please visit my OrcID or LinkedIn profiles. My original research is often avaliable in CentraleSupelec official website. HAL is an open achive initiative of French governement for online communication distribution. Peer-revison is not carried out by HAL, and we strongly advise readers to double check peer-revised versions. According to HAL policy, the deposits must be made in agreement with the co-authors and in the respect for the policy of the publishers, thus some research works cannot be not avaliable.
